help me pls... water with non-mettalic oxides?

Question

a. ) Put a little amount of water into a wide-mouth bottle, then collect some sulfur dioxide by lowering the burned sulfur in the deflagrating spoon into this botttlee.
b.) after aminute, remove the deflagrating sppon and cover the bottle with a watch glass. shkae the bottle then test the solution with red and blue litmus paper.

result:
RED LITMUS PAPER - ____________________
BLUE LITMUS PAPER -___________________

WHAT COMMON EFFECT ON LITMUS PAPER WAS OBTAINED ON CONTACT OF WATER WITH PRODUCTS OF THESE REACTIONS.?

Answer 1

Red litmus paper stayed pink. Blue litmus paper turned pink. I don't understand the middle question. Sulfur burned in air to sulfur dioxide, which reacted with water to produce sulfurous acid.

S + O2 ===> SO2

SO2 + H2O ===> H2SO3

H2SO3 ===> H+ + HSO3- <===> H+ + SO3=
